Overall, the different intermediate-plus IBD strains possess variable early kinetics in the bursal tissues and eliciting antibody (Ab) responses differently withdifferent degrees of bursal lesions. The assessment of the intrabursal vaccine load together with humoral immunity and bursal damage lesion score are fundamental parameters in the evaluation of the intermediate-plus IBD vaccines.
